一、育苗基质的选择番茄幼苗生长要求基质肥沃疏松、透气良好,适宜的pH5.5～7.0。二、种子处理选择发芽率大于90%、子粒饱满、发芽整齐一致的种子。浸种处理,一般用药剂消毒法,温烫浸种和热水烫种易伤害种胚。在药剂消毒之前,先把种子浸水10分钟左右,漂出瘪种子,再行消毒处理。药剂消毒可采取粉剂干拌法或药液浸泡法。用五氯硝基苯拌种能防治番茄苗猝倒
First, the choice of nursery substrate Tomato seedling growth requirements substrate fertile loose, good ventilation, suitable pH5.5 ~ 7.0. Second, the choice of seed germination rate of more than 90%, full of seeds, germinate uniform seeds. Seed soaking treatment, the general use of disinfectant, warm soaking hot and hot water easily hurt seed embryos. Prior to disinfectant, the seeds were soaked for about 10 minutes, bleached deflated seeds, and then disinfected. Disinfection can be taken powder dry mixing or liquid immersion method. Pentachlorobenzene seed dressing can control tomato seedling cataplexy
